Chase is conducting A survey at school to see what their favorite subject is. He surveyed of 25 students from his math class. He found that 75% of the students in math what is their favorite subject. Is this a valid inference? Why or why not? Explain your answer to complete sentences.
Answer:
Not a valid inference.
Step-by-step explanation:
This is not a valid inference. This is because there may be a slight bias from the classmates he is asking, because, as the question read, he is in math class. Asking math class students if they like math or english more, may have a swayed opinion.
Answer:
No
Step-by-step explanation:
This is a biased survey, due to the fact he only asked his classmates in math. For a unbiased survey, everyone must have an equal chance of being picked.
Talon Middle School received 219 prize packs. The school gave away f packs during school fundraisers. There were 42 packs passed out during pep rallies throughout the year. At the end of the year, the school had 54 prize packs left. How many packs were passed out during the fundraiser?
Answer:
123
Step-by-step explanation:
219 - 42 = 177 left
177 - f = 54
f = 177 - 54
f = 123 packs were passed out during the fundraiser
123
Step-by-step explanation:
219-42=177
177-54=123 or (f)
Check your work:
219-42=177
177-123=54
Therefore f=123 or 123 packs were passed out during the fundraiser.

What is the positive solution to the equation 0 = –x2 + 2x + 1? Quadratic formula: x = StartFraction negative b plus or minus StartRoot b squared minus 4 a c EndRoot Over 2 a EndFraction –2 + StartRoot 2 EndRoot 2 – StartRoot 2 EndRoot 1 + StartRoot 2 EndRoot –1 + StartRoot 2 EndRoot
Answer:
See attached for a "Neat" quadratic formula.
a = -1
b = 2
c = 1
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root( 4 -4*-1*1)] / -2
x = [-2 +- sqr root(8)] / -2
x1 = (-2 +2.8284271247) / -2
x1 = .8284271247 / -2
x1 = -0.41421
x2 = (-2 -2.8284271247) / -2
x2 = ( -4.8284271247) / -2
x2 = 2.4142135624

If x + 3y = 7 and x - 3y =7 , then find y
Please help me
Answer:
[tex]x + 3y = 7 , x - 3y = 7 : y = , x = 7[/tex]
Step-by-step explanation:
[tex]\left[\begin{array}{ccc}x + 3y = 7\\x - 3y = 7\end{array}\right][/tex]
Isolate [tex]x[/tex] for [tex]x + 3y = 7 : x = 7 - 3y[/tex]:
Substitute [tex]x = 7 - 3y[/tex]:
[tex]\begin{bmatrix}7-3y-3y=7\end{bmatrix}[/tex]
Isolate [tex]y[/tex] for [tex]7 - 3y - 3y = 7 : y = 0[/tex]:
For [tex]x[/tex] [tex]=7-3y[/tex]
Substitute [tex]y = 0[/tex]
[tex]x=7-3 * 0[/tex]
[tex]7 - 3 * 0 = 7[/tex]
[tex]x = 7[/tex]
The solution to the system of equations are:
[tex]y=0,\:x=7[/tex]

Show your work to prove that the inverse of f(x) is g(x).
f(x)= x+10
-------

g(x)=6x-5
Answer: The inverse of f(x) is not g(x).
Step-by-step explanation:
Steps taken:
Swap x and y variablesSolve for yProve that the equations of f'(x) and g(x) are identical.1.
[tex]f(x) = x + 10\\y = x + 10\\x = y + 10[/tex]
2.
[tex]x = y + 10\\y = x - 10[/tex]
The inverse of f(x) is x - 10, which does not match with g(x).
A total of 544 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold?
Answer:
x=136
Step-by-step explanation:
So lets say x is the number of pencils so, the number of erasers = 544-x
The equation is then 3x = 544-x & x=136
Answer: 136 adult tickets
Step-by-step explanation: If you have 136 adult tickets then you have to multiply that by three in order to get the child tickets. 136 x 3 = 408 and 408 + 136 = 54

Answer: i think its the first one 2/3
Answer:
2/3
Step-by-step explanation:
it starts off as 2:3 right? so the 3 is light soy sauce. if you want to turn the right soy sauce into 1 cup you have to divide 3 bye 3 which gives you one. then you also divide by 3 on the other side. that would be 2 divided by 3. 2 divided by 3 is the same as 2/3. so your answer is 2/3.
Your savings account pays 2.5% interest per year. How much interest does the account pay per month.
Answer:
0.21%
Step-by-step explanation:
2.5/12=0.208 or 0.21
Based on the interest that your savings account pays per year, the interest paid per month is 0.21%.
How much interest is paid per month?The interest paid per month can be found by dividing the yearly interest by the 12 months of the year.
Therefore, solving gives:
= Annual interest / 12 months
= 2.5% / 12
= 0.21%
In conclusion, this is 0.21%.

1) how many bases does it have
2) what is the figure called
Answer:
its called triangular pyramid
and it has one base
Step-by-step explanation:
2. In the diagram below, secants PT and PU have been drawn from exterior point P such that the four arcs
intercepted have the following ratio of measurements:
P
mRS : mST :MTU : mUR=1:4:4:3
R
(a) If mRS = x, then write an equation that could be used to solve for x
and find the value of x.
I
4
(b) State the measure of each of the four arcs.
mRS =
mST =
MTU
MUR =
Answer:
(a) x = 30°
(b) mRS = 30°
mST = 120°
mTU = 120°
mUR = 90°
Step-by-step explanation:
(a) In the picture attached, the diagram is shown.
Given that m arc RS = x, from the ratios:
m arc ST = 4x
m arc TU = 4x
m arc UR = 3x
The addition of the four arcs must be equal to 360°, then:
x + 4x + 4x + 3x = 360°
12x = 360°
x = 360°/12 = 30°
(b) m arc RS = x = 30°
m arc ST = 4x = 4*30° = 120°
m arc TU = 4x = 4*30° = 120°
m arc UR = 3x = 3*30° = 90°

P(B) = 0.35
P(C) = 0.55
What is the probability of the complement of Event B?
0.85
0.35
0.65
0.45
Answer:
0.35
Step-by-step explanation:
The probability of the complement of Event B is equal to 0.65. so option C is correct.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
Given;
Event A and Event B are mutually exclusive.
We have given data
P(A) = 0.15
P(B) = 0.35
P(C) = 0.55
We need to find the he probability of the complement of Event B.
The formula for the compliment of the event
P( B⁻ ) = 1 - P( B)
Use the given value in the above formula we have,
= 1 - 0.35
= 0.65
The probability of the complement of Event B is equal to 0.65. so option C is correct.
